How the hotel's automatic doors are automatically opened and closed
Infrared detection, people come after the infrared detection, open the door, people left, the delay closed
(1) the main controller: it is the command center of the automatic door, through the internal editing instructions program (1) the main controller: it is the command center of the automatic door, through the internal instructions of the program Large-scale manifold block, issued a corresponding command, command motor or electric lock system work; the same time through the master to adjust the door opening speed, open amplitude and other parameters. (2) sensor detectors: responsible for collecting external signals, like people's eyes, when a moving object into its scope of work, it gives the main controller a pulse signal;
(3) power motor: to provide the door and closing the main force to control the door to accelerate and slow down the operation. The following are the same as the "
(4) the door into the track: like the train rail, the constraints of the door of the spreader wheel system to make it in a specific direction. (5) door spreader wheel system: for hanging activities of the door, while driving the door under the power tractor running. The following are the same as the "
(6) synchronous belt (some manufacturers use V-belt): for the transmission of motor power, traction door spreader wheel system. (7) the lower guide system: the lower part of the door guide and positioning device to prevent the door in the running before and after the door swing. (8) automatic sensor door equipped with induction door machine, is to control the automatic door to open and close a series of components together; also known as automatic door unit or sensor door unit; induction door machine components generally include: motor, controller, Pulley, belt.
Automatic sensor door workflow is as follows:
When the sensor detects that someone enters, the sensor detector will collect the signal, generate a pulse signal, followed by the pulse signal to the master, the master to inform the motor after the judge, while monitoring the motor speed, in order to inform the motor in a certain When the force and into the slow running. The motor is given a certain running current to do a positive run, the power transmitted to the timing belt, and then by the timing belt will be passed to the spreader system to open the door; door opened by the controller to make judgments, if closed, notify the motor To move, close the door.
